Filter Designer App Panels

The Filter Designer app has sidebar buttons that display particular panels in the lower half. The panels are:

• Design Filter. See Choosing a Filter Design Method for more information. You use this panel to

  • Design filters from scratch.

  • Modify existing filters designed with the app.

  • Analyze filters.

• Import filter. You use this panel to

  • Import previously saved filters or filter coefficients that you have stored in the MATLAB^® workspace.

  • Analyze imported filters.

• Pole-Zero Editor. See Editing the Filter Using the Pole-Zero Editor. You use this panel to add, delete, and move poles and zeros in your filter design.

If you also have DSP System Toolbox™ product installed, additional panels are available:

• Set quantization parameters — Use this panel to quantize double-precision filters that you design with Filter Designer, quantize double-precision filters that you import into the app, and analyze quantized filters.

• Transform filter — Use this panel to change a filter from one response type to another.

• Multirate filter design — Use this panel to create a multirate filter from your existing FIR design, create CIC filters, and linear and hold interpolators.

If you have Simulink^® installed, this panel is available:

• Realize Model — Use this panel to create a Simulink block containing the filter structure.
